Fusidic Acid is an antibiotic used primarily to treat bacterial infections, particularly those caused by Staphylococcus aureus. It works by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. This medication is often available in topical forms, such as creams and ointments, for skin infections, as well as in oral and injectable forms for more severe infections. While generally well-tolerated, it can cause side effects like skin irritation or allergic reactions in some individuals. Always consult a healthcare professional before use.
